- Collaborate with data operations to design task curricula and evaluation protocols

- Own environment deployment and reliability

- Rapidly prototype new environment types

## What We're Looking For

- 2+ years of professional software engineering experience with strong fundamentals in Python and at least one systems-level language

- Demonstrated experience with containerization and sandboxing

- Familiarity with RL concepts

- Experience building or maintaining developer tooling, CLI tools, or infrastructure automation

- Comfort working with browser automation frameworks or terminal interaction tooling

- Strong debugging instincts

- Ability to read and implement from academic papers and open-source benchmark repositories

## Why This Role Matters

- Reinforcement learning has become the state-of-the-art approach for training agentic AI, and environment quality is one of its biggest bottlenecks

- You'll work across a portfolio of projects spanning different AI labs and model capabilities

- Alignerr is a small, high-impact team inside Labelbox with startup-level ownership and growth-stage resources
